We are actually in the lower deserts here, so even hotter than the higher deserts by about 10 degrees in summer... ;) Of course as you know, once it reaches 100+, it all feels the same, nasty.
I have been to Tombstone many times, and saw the worlds largest rose tree, being the rose fanatic that I am. I just love Tombstone. All the locals down there are so friendly, and I always have a great time when I got down to visit them. I almost bought a bed and breakfast down there, the only Victorian home left in downtown tombstone, that was not destroyed when the town caught on fire. I'm not sure if you'll remember it, it was called Pricilla's bed and breakfast, a grand old five bedroom lady, with a private owners quarters, separate from the B&B. Was perfect. Long story short, she was asking more than it's worth, had no proof of how much she was making a year, and I was not willing to give her what she was asking without any proof of income. I heard 2 years later, she sold it for what I was willing to pay her for it. Oh well, life goes on. So love it down there. I may retire down there.
